Also, as shown in FIG. 2, the structure of the supporting surface 5 of the side groove 1 is greatly different in that it is formed of a curved surface having a concave cross section. The concave curved surface of the support surface 5 of the gutter 1 is substantially similar to the convex curved surface of the contact portion 11 of the gutter lid 10. That is, this difference is a feature of the envelope-shaped gutter of the present embodiment.

FIG. 3 is a sectional view showing a construction state of the envelope type gutter which is the first embodiment of the present invention. To install the envelope-shaped gutter, first, the installation groove is dug to adjust the level of the ground at the installation site. Then, as shown in FIG.
The foundation stone layer 23 is formed by laying ground stones, pressing with a rammer or the like, throwing out discarded concrete, and aligning and leveling the upper surface slightly lower than the installation surface of the encapsulation type gutter.
Next, in order to determine the exact installation surface of the encased gutter 1, the basic concrete is struck and leveled, and the basic concrete layer 22

Finely adjust the level by laying a liner, etc., hit the finished concrete from the opening 4, stir the stick along the lower part of the inner surface of the vertical support member 3 with a stick, etc. The bottom surface of the base concrete layer 22 and the top surface of the basic concrete layer 22 are filled until all the gaps are filled, and the exposed portion of the top surface of the finished concrete is evened to form a water bottom surface 21a.

Next, a method of constructing the encased gutter according to this embodiment will be described. FIG. 4 is an explanatory diagram showing a construction situation of the encapsulation-type gutter which is the first embodiment of the present invention, and FIG. 4 (a) is an explanatory diagram showing a construction situation of the encapsulation-type gutter in the side direction,
(B) is explanatory drawing which shows the installation condition of the encapsulation side gutter by the front direction.

As shown in FIGS. 4 (a) and 4 (b), the gutter 1 of the encapsulation-type gutter is installed by using two supporting carriages 30. The support cart 30 includes a base member 32, a height adjusting unit 31 disposed above the base member 32 and capable of supporting a heavy object such as the side groove 1 such that the height of the base member 32 can be adjusted vertically. And a caster 33 for freely supporting the movement of the base member 32 in the horizontal direction. This support cart 30
When the height of the height adjusting portion 31 of the
It has a size that can be stored in a space surrounded by the horizontal support member 2 and the vertical support member 3, and when the height of the height adjusting portion 31 is the highest, the horizontal support member 2 of the side groove 1 can be supported. ,
The lower surface of the vertical support member 3 can be separated from the upper surface of the foundation concrete layer 22. In the above description, in order to arrange the gutters 1 on the upper surface of the foundation concrete layer 22, first, the plurality of gutters 1 carried by a vehicle such as a truck are covered with an unic or a crane on the upper surface of the foundation concrete layer 22. Properly arrange the mold gutters in the vicinity of the planned construction position in a scale. Then, each side groove 1 is supported by two supporting carriages 30 and is appropriately moved in the horizontal direction and the vertical direction to accurately position the installation place, and after the installation position is determined, the lower surface of the vertical support member 3 is removed. The gutter 1 is temporarily installed in the gap formed between the upper surfaces of the foundation concrete layers 22 with a liner or the like interposed therebetween, and the height adjusting unit 31 is lowered to lower the support carriage 30.
Remove. After the temporary installation of the first gutter 1 is completed, the adjacent gutters 1 are sequentially temporarily supported and all the gutters 1 are temporarily supported.
After the temporary installation of No. 1 is completed, the work for hitting the finished concrete layer 21 is started.

When the work of the finished concrete layer 21 is completed, the mortar is inserted into the joint groove 3a of each of the gutters 1 to completely fill the gap between the adjacent gutters 1 and the opening of each gutter 1 is opened. The part 4 is closed with the gutter cover 10.
In each gutter lid 10, the contact portion 11 is supported by the support surface 5 of the opening 4 of the gutter 1, and the upper surface of the horizontal support member 2 of the gutter 1 and the upper surface of the gutter lid 10 are substantially flush with each other.

Next, another construction method for the envelope-shaped gutter of this embodiment will be described. FIG. 5: is explanatory drawing which shows the other construction state of the envelope type gutter which is 1st embodiment of this invention.

In FIG. 5, envelope type gutters are installed along the sides of the road, and the upper surface of the envelope type gutters is placed on a vehicle 40 such as a passenger car.
Is passing. In the installed state of the encased gutter as shown in FIG. 5, the upper surface of the gutter is along the road surface of the substantially horizontal road, whereas the water bottom surface of the water channel formed inside the gutter is inclined. That is, the envelope-shaped gutter used in the construction shown in FIG. 5 is formed by inclining according to the angle of the water channel in which the lower portion of the vertical support member 3 inclines. With a normal U-shaped gutter, if the angle between the top surface and the bottom surface of the water is changed according to the site, a mold for the gutter must be newly manufactured.
In the case of a custom order, it was a very expensive gutter. However,
In the envelope-shaped gutter of the present embodiment, since there is no bottom member in the lower portion of the vertical support member 3 and the structure is very simple, the molding portion of the vertical support member 3 of the standard-type envelope-shaped gutter forming mold. Only by extending the above, it is possible to easily provide a gutter that meets the purpose, and the manufacturing cost is low. In this construction, the support cart 30 is naturally used.

Therefore, the envelope-shaped gutter of this embodiment is
When positioning on the upper surface of the foundation concrete layer 22, it can be easily positioned by the support truck 30, and the need for a unic or a crane is only in the temporary arrangement, and the usual U
It is very safe and does not require a unic or crane until positioning is completed like a gutter-shaped gutter, and it is very short in the time of obstructing traffic.

In particular, the envelope-shaped gutter of the present embodiment has a gutter lid 10 having an abutting portion 11 having a curved surface having a convex cross section, and an opening 4 that can be closed by the gutter lid 10 as a horizontal support member 2. Of the horizontal support member 2 at the substantially center of the upper surface of the horizontal support member 2, and at the end of the opening 4 is a support surface 5 having a curved surface with a concave cross section that is substantially similar to the curved surface of the contact portion 11 of the gutter lid 10. Since the vertical support member 3 is formed of the gutters 1 that extend downward, the gutter cover 10 does not rattle and noise does not occur even when a vehicle or the like passes over the upper surface after construction.

That is, since the support surface 5 supporting the gutter lid 10 receives a force, the vertical load acting on the gutter lid 10 is applied from the contact portion 11 of the gutter lid 10 to the gutter 1 because the support surface 5 is a curved surface.
Since it is dispersed through the supporting surface 5 and transmitted to the side groove 1, and the adhesion between the side groove cover 10 and the side groove 1 is improved,
There is no rattling due to the imbalance of the force applied to the upper surface of the gutter lid 10, and no noise is generated. Further, since the supporting surface 5 does not have a flat portion, pebbles, gravel, soil, and the like are less likely to be deposited, and even when they are deposited, it is very easy to remove them, so that it is easy to mount the gutter lid 10. In addition, the lower end of the supporting surface 5 is formed with a barbed portion 5a, and a predetermined gap is formed between the lower end of the contact portion 11 of the gutter cover 10 and the lower end of the supporting surface 5 of the gutter 1. Therefore, after the construction, gravel, soil and the like gather in this gap, and the contact portion 11 of the gutter lid 10 and the supporting surface 5 of the gutter 1 are kept in surface contact with each other. Furthermore, when a vertical load is applied to the gutter lid 10, the contact surface between the gutter lid 10 and the gutter 1 is a curved surface, so that the action directions of the force lines are dispersed,
The load on the gutter lid 10 and the gutter 1 is reduced, and the service life is extended.

That is, in addition to the function and effect of the conventional encased gutter, the encased gutter of this embodiment has the gutter lid 10 wobbling even when a vehicle or a person passes over the upper surface of the gutter lid 10. Therefore, noise is not generated, and when the gutter lid 10 is removed for installation work or maintenance inspection of the encased gutter 50, it is difficult for pebbles, gravel, soil, etc. to be deposited on the support surface 5, and even when they are deposited. Very easy to remove.

In the above description, the work of striking the finished concrete layer 21 is not necessarily performed after all temporary installation of the encased gutter on the upper surface of the basic concrete layer 22 is completed, but the basic concrete layer of the gutter is completed. It is also possible to sequentially shift to the work of striking the finished concrete layer 21 in order from the gutter 1 in which provisional installation on the upper surface of 22 is completed.

Further, in the above description, the work of inserting the mortar into the joint groove 3a is not limited to the completion of the work of the finished concrete layer 21, but the adjoining covered grooves in the temporarily supported state of the encapsulation side groove. If the envelope-shaped gutter is temporarily installed,
Regarding the joint groove 3a between the adjacent encapsulation side grooves,
Mortar insertion work may be performed.

[0031]

As described above, the encapsulated side groove of the present invention is
Since the shape of the support surface that supports the gutter lid of the opening formed in a part of the horizontal support member is a curved surface, and the contact portion of the gutter lid is also a curved surface, the load received from the gutter lid is dispersed. As the vehicle and the person pass over the upper surface of the gutter lid, rattling does not occur and noise is not generated. In addition, since there is no flat surface on the support surface, pebbles,
Since it is difficult to deposit gravel, soil, etc., and it is very easy to remove even when it is deposited, it does not take time to mount the gutter lid.
